The present disclosure relates to a backlight module and a liquid crystal device. The backlight module includes a LED light source and a lens bar. The LED light source is arranged on the LED substrate and includes a plurality of LED lamps encapsulated by CSP. The lens bar is arranged in the front of the LED light source and includes a plurality of chambers. Internal walls of the chambers are parabola-shaped curved surfaces. Each of the LED lamps is arranged in a rim of a focal point formed by the parabola-shaped curved surface such that the curved surface above the LED lamps is symmetrical to that below the LED lamps. With such configuration, the LED light source encapsulated by the CSP may be incorporated in edge-type BLU so as to avoid the optical leakage issue.
